'Thief' in the Bible

"Truly, truly I say to you, the one who does not enter through the door into the fold of the sheep, but climbs up at some other place--that one is a thief and a robber.

The thief {comes only} so that he can steal and kill and destroy; I have come so that they may have life, and have [it] abundantly.

(Now he said this not because {he was concerned} about the poor, but because he was a thief, and having the money box, he used to steal what was put into [it].)
